"Can we extract a sample?" Zhang Qutong turned around and asked the technician.
"I don't know, give it a try." Under the control of technicians, the large intelligent robotic arm of the "Wangshu" intelligent lunar surface patrol and exploration vehicle subsequently replaced a professional drilling component, and then aimed at the brown stone.
Start drilling.
In order to extract rock samples from inside the lunar rock, technicians specially prepared a professional exploration drill bit for this "Wangshu" intelligent lunar surface patrol and exploration vehicle, so that it can drill into the lunar rock and extract the lunar rock.
the substance inside.
But for the core of this asteroid, it was a bit difficult for this drill to drill. The drill was rotated and rubbed at high speed on the surface of the core. It took a long time to drill in, and some powdery material was brought out by the rotating drill.
However, the drilling work did not stop, but continued to deepen. It was not until about half an hour of drilling that the drill bit penetrated about 20 centimeters into the core of the star, and the drilling work ended.
Immediately, the large robotic arm retracted, and the small robotic arm began to collect the drilled powdery materials.
"Put it in the experimental cabin immediately." Seeing these materials, the experts couldn't help but become anxious. They all now want to know the composition of this star core. You must know that the cores of these asteroids may contain the formation of the solar system and even the universe.
It is a mystery, so everyone is full of expectations for this detection and analysis.
Of course, they were in a hurry, and everything still had to be carried out according to the procedures. After first completing the collection, packaging and labeling of these star core samples, they then placed the remaining samples on the experimental platform in the test site and in the test chamber.
The instruments and equipment analyze the star core samples on the experimental platform.
The waiting process always makes people anxious, not only the experts, but also the netizens watching the live broadcast channel on the Internet. Netizens are very excited about the discovery of the star core. Especially the material components inside the star core can be extracted
Samples, which are of very high value for asteroids, the formation of the solar system and even the formation of the universe. Such an opportunity is very rare, making netizens say that they have made a profit today and it is an eye-opener.
The entire detection and analysis took about forty minutes to complete, and then a magnified photo of a sample of material components in the star core appeared on the big screen.
Because it is drilling, the samples extracted are fine powders, but this is good, so that the components in these star core samples can be analyzed more clearly.
Photos under the microscope show that the substances in these samples are still very rich. In addition to brown particles, there are also particles of other colors. The most eye-catching among them are the tiny particles with sparkling silver. Through elemental analysis equipment,
Soon the analysis and detection data information transmitted by the "Wangshu" intelligent lunar surface patrol and exploration vehicle was displayed on the big screen.
Looking at the table of elemental contents in the samples displayed on the big screen, the experts all became excited.
"This is a rare platinum asteroid. I asked you why it was so hard when drilling." An expert took a breath of cold air and said.
Another expert said with emotion: "The platinum asteroid is worthy of the name, its content exceeds 42%. According to the reminder of this star core, it is estimated that more than one ton of platinum can be extracted from it. According to one ton
Calculating, the price of platinum has risen rapidly in recent years, about 400 yuan per gram. This ton of platinum is one million grams, multiplied by 400, this is 400 million. If nothing else, just
By transporting this star core back, we can recoup the cost of our exploration mission, and even make a lot of money."
"Vulgarity, the scientific research value of this star core is far more precious than money. Didn't you see that besides platinum, there are other substances in it."
"Really, in addition to platinum, there is also 1% gold, 3% copper, 7% titanium iron, and the rest is quartz. The composition of glass has even been detected. This is not
It should be considered glass, its Mohs hardness has reached the level of ruby, it is really a gem."
"Logically speaking, the energy generated by the impact of a star core like this should not just form a small crater that is one to two hundred meters in size and 20 to 30 meters in length. Moreover, such a star core should also be drilled into the underground of the crater.
, how can it be exposed on the surface? This is too abnormal."
"It's very abnormal." The experts couldn't help but nodded after hearing this. Indeed, the moon's gravity is small, but there is no atmosphere, and there is no problem of friction and combustion deceleration. Therefore, asteroids generally hit the surface of the moon directly.
, which is why there are so many large and small craters distributed on the surface of the moon.
In addition, these asteroids fly very fast in space. In addition to being affected by the gravity of the sun, they are also affected by the speed of various planets, so these asteroids fly very fast in space. In addition, the earth and
The influence of the moon's gravity, based on the visual size of the asteroid's core, is absolutely impossible to form just such a small crater.
The experts frowned and thought for a while, and one expert came up with an idea of his own: "Could it be that the core of the star was not directly impacted, but was formed by a secondary impact?"
"A secondary impact?" Other experts asked with some confusion.
"Yes, could it be part of the splash-out after the impact of other large asteroids?" the expert expressed his thoughts.
Experts shook their heads and expressed their objections after hearing this. How is this possible? Even if there are flying fragments after the meteorite falls on the moon, it should fall at an angle instead of such a regular circular crater.
"Then there is another possibility."
When this expert saw other experts denying it, he was not angry, but immediately came up with another guess: "This asteroid should have been captured by the moon. After flying around the moon for a long time, its speed dropped and was affected by the moon's gravity.
The impact finally fell. In this way, it did not fall very fast, so it did not produce much power, and the crater formed was relatively small. This can also explain why the core of this asteroid is exposed in the
The reason why it is on the ground instead of drilling into the underground of the crater.”
After hearing this conjecture, many experts thought for a while and then nodded. Although this conjecture is a bit bold, it is still relatively reasonable. The asteroid is affected by the gravity of the earth and the moon, thus changing its original flight orbit. Because of the speed and
Due to the angle, it accidentally cut into the lunar orbit, and was captured by the lunar orbit and began to orbit the lunar orbit. Affected by the gravity of the moon and the gravity of the earth, the asteroid's flight speed and orbit gradually decreased, and finally hit the moon.
superior.
Only in this way can we explain why such a huge meteorite core formed when it hit the moon's surface, and why such a small crater was formed after it hit the moon.
